Meryl Streep has been working on her rap skills, James Corden has revealed.

The three-time Oscar-winning actress has been learning to rap for a song in their new film, Into The Woods, and James - who previously collaborated with rapper Dizzee Rascal on World Cup song Shout - has been impressed with her lyrical dexterity.

"She's less an Eminem, more a 50 Cent type. Mainstream with an edge," he told The Sun.

James said her enunciation skills helped her rap and joked "a second career beckons".

The Iron Lady star plays The Witch in Into The Woods, Rob Marshall's big-screen adaptation of Stephen Sondheim's Broadway musical, while James portrays The Baker.

Johnny Depp, Emily Blunt and Anna Kendrick also star in the film, which is scheduled for release in December.
